HOPPER-BOTTOM DUMP-CAR.

T o all wlw/ml t may concern:

Be it known that I, CLAUS J.' WERNER kCLASEN, a citizen of the United States of 4 America, and resident of Davenport, Scott county, Iowa, have invented a certain new and use-ful Improvement in Hopper-Bottom Dump-Cars, of which the following is a specification.

My invention relates to improvements in dump cars of the hopper bottom type, wherein the hoppers are arranged on each side of the longitudinal center of the car. Usually these hoppers are formed b y the swinging drop doors when in their closed position. My invention, however, contemplates a series of fixed hoppers arranged on each side of the longitudinal center of the car and transversely theretothe object being to convert the entire floor area into a multiplicity of scoop like hoppers with discharge openings, whereby materials can be loaded over the entire floor surface and yet be automatically discharged; whereas, at present, the loading and discharging is confined principally to that portion of the floor area located between the body holsters of the car body, thus greatly, reducing its carrying capacity. When the entire floor, including thatportion between the body bolsters and the 'ends of the car, is formed of drop doors, the car body is soon twisted out of shape due to the absence of diagonal bracing such as would be afforded by .'f'solid floor and it is therefore the general practice to provide discharge openings or hoppers betweenthe trucks only, leaving the remain-` ing portion of the floor solid toinsure proper strength to the structure as a whole. It then becomes necessary to partition off those portions of the car, thereby reducing its carrying capacity or permit the ends to become filled and then, on emptying the car, manually remove that portion of the load. The object of my invention is to not only provide automatically dischargeable hop pers throughout and make the entire floor area available for load carrying purposes,

A but also to produce strength and stitiness to the entire structurctoan extent even greater than that a'liorded by the ordinary solid floor. These and other objects, which will hereinafter appear, I attain by the structure illustrated in the aceompanyingdrawings, in Which'- Patented Aug'. 26,1913.

Figure 1 is a vertical cross section of a gondola car through the center sill and hoppers, taken on line A. B. of Fig. 3 looking to the right or toward the needlebeam. Fig. 2 is a similar view looking to the left or toward the body bolster. Fig. 3 is a plan view of one end of a gondola car showing one type of hopper on one longitudinal center and another type on the other side. Fig. 4 is a side elevation of the same portion of a gondola as shown in Fig. 3 and shows an end view of both styles of hoppers. Fig. 5 is a perspective view of a hopper having a restricted discharge opening. Fig. 6 is a perspective view of a hopper with an unrestricted openmg.

Similar numerals refer to throughout the several views.

The center sill 2, body bolster 3, truck bolster 4, end sill 5, needle beam 6, side walls 7, stakes 8 and end walls 9, form the underframeand sides of the car and are of usual construction for cars of this kind. Instead of a solid or stationary floor covering the entire area of the car bottom, or a floor made up of drop doors in that porsimilar parts Side 0f their tion between body holsters, and solid or stay tionary floor sections betwecn'the holsters and ends of car, I provide a floor, extending over the entire bottom from end to end'of car, made up of the scoop like hoppers 10, arranged in two rows, one on each side ofthe longitudinal center of the car, each hopper occupying the entire space between adjacent transverse members of the underframe. The spaces between the holsters 3 and end sills 5 also being occupied by these hoppers and not covered by a fixed floor plate lying flat as is the usual custom in gondolas, or by the long slope sheet generally employed in center dump ore cars or cars of that type. Not only Iis the rigidity of the car thus assured and the entire floor area capable of being dumped, but the carrying capacity of the `car is also greatly increased over that of the drop bottom car with sides of equal height. And again as the carrying capacity of the hoppers themselves represents a large percentage'of the entire capacity, vthe center of gravityA of the entire loaded car, as a unit, is great] and beneficially lowered. These hoppers 0 are preferably 'formed of two sheets pressed into proper form as shown in Fig. 5 or can be made from a single sheet as shown 1n `Fig. 6. In the preferred form, one sheet forms the bottom'and lsides of the scoop like hopper and the other formsthe outer end l1 which is provided with discharge opening 12. The upper marginal edges 13 o-f the sides of the hoppers extend perpendicula-rly in order to contact the vertical webs of. the transverse members to which they arexriveted as shown at 14, whil' the rear or Hp end 15 of the hop ers 'e tend horizontally, fitting in under an up against the under 4surface 16 of the eye beam vtft-.inge forming the center sill,2, to which they are securely riveted. aAs shown in Fig. 5 the discharge end of the hopper, in its preferred form consists of the flanged 'plate 11 protinuous from end to end o divided at the center, each half being opervided with the flanged opening 12 and the outwardly extending a'nge 17. This plate yis, riveted. to the downwardly extending flange 17a of the hopper. The flange 17 is rivetedto the car sides as shown at 18.

Extending the entire length of the car' on each side thereof in the vicinity of the upper part of the hopper openings, is-the combined hinge and door lock operating shaft 19. This shaft is supported at its ends in a suitable bearing (not shownl located in the end sill 5, and also by the hangers 20. If hoppers with full openings are employed this shaft is located a trifle higher up and supported by the` shorter bearings 21. The 'doors 22 are swingingly mounted on this shaft bythe hinge castings 23.- Door' latches 24, which are pivotally *secured tothe doors and which normally rest back of the hasps' 25 when the doors are in'closed position, are operatively connected to the hinge shaft 19 by the chains 2 6. Itis' thus seen that by revolving this hinge shaft by any suitable means at the end of the car, all the doors on one side of the car can be unlocked and permitted to swing openf as shown by the door in dotted lines in Figvl. Instead of makin the shaft concar it can be ated independently from each end of the carand thereby one half of the floors openedat a time if found desirable-a situation frequently arising in practice.

I am aware that hopper bottom cars have been made wherein the hoppers extended over the entire fioor arca, but these hopper-s were of that type in which the load was discharged straight down between the rails bythe use of swinging doors lying fiat or horizontal, in the bottom of he hoppers, when in closed position. Thus the ioor proper was made np of a large number of 'sistance to the rack Yllering iitle or no rec and twisting strains to which dump are subjected. 'This also truc, to an even greater extent, in

articulated parts. o

that type of dump cars in which the hopper sides or bottom are made up of movable floor sect-ions, or of tbe swinging doors themselves.

In my improved construction it is seen d walls, transverse members including end v sills, body holsters, needle beams endend walls; side-deliver chute-like hoppersllilling all'the spaces orm'ed by the intersection of the longitudinal and transverse members, and their greatest portion depressed be-' low the plane thereof.

2. A hopper bottom car` the entire horizontal area of which consists of side-delivery chute-like individual hoppers, said hoppors being divide in two longitudinal side-byside, series extending from end to cnd of the car body between the cross-members, the discharge end of said hoppers being depressed below the plane of the car bed or frame.

3. A hopper bottom car, intersecting longitudinal and transverse floor framing members, one-piece chute-like hoppers, each rigidly secured to 'the adjacent intersecting members along their upper edges and ex- .tending substantially to the level of the top plane of the floor members, and having their discharge ends approximately in the i vertical plane of the car sides and depressed below the plane of the said floor members.

4. A'hopper bottom car having a floor consisting of framing members and onepiece hoppers rigidly secured thereto, vertically hung 'doors engaging the discharge end of said hoppers andcombined hinge and door lock operating shafts supporting said doors. l

5. A hopper bottom car having permanent upright sides, ends and intersecting fioor members, integral side-delivery hopA pers permanently secured to said floor members in the spaces formed by said intersections and extending substantially to the level of the top plane of said Hoor beams.

6. A hopper bottom car having permanent upri ht sides, ends and intersecting floor mem rs, ,integral side-delivery hopprs permanently secured to said floor mem- Vbers inx the spaces formed by said intersections1 vertically hung doors engaging the discharge end of said hoppers, and combined binge and door lock Voperating shafts supporting said doors.
